Dissemination via smartphone PROJECT
The workshops covered the following topics: Conservation with traditional materials and techniques
Material investigation Building diagnosis pathology study, thermal imaging,
endoscope Site analysis aerial photography, site survey
Regional planning remote sensing – GIS Interpretation – story telling, historic routes
Tourism Technology
The specific venue for these exercises was developed in coordination with on-going restorationconservation works in
Stolac. The primary focus was centered on the cultural heritage of Stolac - river objects, mills and bridges, as well as the Saric
family house in Stolac, Branko Sotra Gallery and part of the complex of “Old Town Vidoski”.

Information capture
During the courses many exercises were devoted to collection and mapping of the images. The capture technology that was
used included the use of 14 GPS enabled Nikon Coolpix Aw30 cameras, tablet computers and smartphones to collect geo-
referenced images of monuments, mills and bridges. The use of this technology allowed the community and team to build an
inventory of places and monuments important to the community as well as update the official list of protected monuments. A
defined protocol was taught during the courses and implemented for the capture of the images but with enough
emphasis on flexibility to allow the participants to record what was important to them. This protocol included what time of day
to capture the image, angle, general photography principles and note taking Eppich, 2007. The images as well as being spatial
located were also organized along with the name of the monument, date and other key information making possible the
indexing and archiving of these records. The photogrammetric 3 x 3 rules were used to capture images of monuments that were
in total or partial ruin in order to collect sufficient data to create 3D models CIPA, 2013. This information was augmented with
field measurements and the School of Architecture created these models using Photomodeler, Autocad and 3D Max. It was
essential that the models were created with a low polygon count and reduced resolution textures as these had to be visible on
smartphones. Numerous tests were conducted to ensure that these portable devices could process the 3D models.
In the project the simple on-line collaborative tool Google Map was used to plan the courses, work schedules, identify
monuments, review images and verify results. This free on-line tool made it possible to conduct meetings in real-time between
Stolac, Sarajevo and Bilbao. As participants uploaded the images, descriptions and measurements during the courses they
were
visible to
invited participants
and partners.
Understandably, the course participants produced many more images, data files and documentation than could be used in the
final smartphone application therefore editing by the team was necessary. Nevertheless it gave the project team and participants
an understanding what was important to the community and what to include in the final application and assist in planning
the eventual visitor cultural routes.
This highlights that many tools do not have to be difficult to use, expensive or sophisticated in order to be effective. All the
tools were left with the school and tourism association in Stolac. An example is available at: www.connectingstolac.ba.
